A ball has an initial velocity of 10 m/s.(adsbygoogle = window.adsbygoogle || []).push({});

The acceleration of gravity is 9.8 m/s^2.

What will be it's postion after 2.12794 s if it is throw

a) down with an initial velocity of 10 m/s? Answer in units of m.

b) up with an initial velocity of 10 m/s? Answer in units of m.

I think for b you use:

y = Vot + 1/2gt^2

I got 43.47m, but thats wrong.
